Stellantis (FCA US, LLC) has been granted a groundbreaking patent for an Electric Drive Module (EDM) featuring an integrated winch system. Originally filed with the U.S. Patent and Trademark Office (USPTO) on January 25, 2024, and officially granted on January 21, 2025, this innovation could play a crucial role in the future of electrified Jeep® off-road capability.
A New Era for Electrified Off-Roading –
The patent details a unique gearbox assembly that allows an electric motor to selectively provide drive torque to the vehicle’s wheels or an integrated winch. This dual-mode functionality means off-road enthusiasts could soon benefit from a built-in winch without needing an external electric or hydraulic system.
How It Works –
The EDM features a differential that distributes torque to the front or rear axles in standard driving conditions. However, when switched to winch mode, the system redirects power from the electric motor to a planetary gear set, which then drives the winch spool. This design eliminates the need for a separate winch motor, reducing weight and complexity.
Key Features of the Patent –
One of the standout features of this patent is its integrated winch system, which utilizes the vehicle’s primary electric motor instead of requiring a separate winch motor. By doing so, Stellantis has effectively streamlined off-road recovery equipment while maintaining efficiency. The integrated design means Jeep models could house the winch within the front fascia or engine bay, keeping it protected and aesthetically unobtrusive.
Another critical innovation is the planetary gear set, which enables power redirection from the electric motor to the winch spool when engaged. This setup ensures that power is efficiently delivered without the need for additional mechanical components, reducing overall system complexity. The planetary gears play a crucial role in seamlessly switching between drive and winch modes without unnecessary power loss.
The drive mode switching capability is another key aspect of this patent. Drivers will be able to transition smoothly between propelling the vehicle and activating the winch with minimal effort. This feature could be integrated into Jeep’s existing drive mode selector, making it an intuitive addition for off-road enthusiasts. Whether stuck in deep mud or navigating rocky terrain, the ability to instantly engage a winch powered by the electric motor adds a new layer of convenience and capability.
Furthermore, the compact design of this system significantly reduces the need for additional mounting space compared to traditional winches. By integrating the winch within the EDM, Jeep and other Stellantis vehicles could maintain their rugged, factory-built aesthetics while enhancing recovery capability. This system could also help maintain better approach angles and minimize external modifications often required for aftermarket winch installations.
What This Means for Jeep® and Stellantis –
Jeep vehicles, particularly models like the Wrangler and Gladiator, have long been associated with extreme off-road capability. If Stellantis integrates this technology into future models, Jeep owners could benefit from an electric-powered winch that is always available without requiring separate installation.
The patent suggests a focus on integrating the spool behind the front fascia or within the engine bay, making it a streamlined solution for off-road recovery. Additionally, the system’s reliance on an existing electric motor means it could be used across Stellantis’ expanding lineup of electrified SUVs and trucks.
